44 square meters, the house in 2000, because the leakage switch is always blocked, the property said that the wires in the house are broken and need to be replaced.

1. The property is right. If it is a buried wire, it is very difficult to check the leakage point, and there may be more than one. The workload of these investigations is no less than that of the new cable layout. Therefore, in order to deal with the problem of leakage tripping, rewiring is a better scheme.

2. "I think there should be something wrong with a wire at home. Why is it necessary to change all the wires again? " Again, it's not necessarily just a broken place.

3. Be cost-conscious. For example, when sewing in the dark, a needle fell to the ground and I couldn't find it at the moment. But there are other needles available on the table. How should you make a decision? Looking for needles all night? The needle hasn't left the house, so you should be able to find it.
